Mary-Kate and Ashley Olsen are adding a new feature to their growing lifestyle brand: fragrance.

The perfume duo, which the twins named Nirvana, will be associated with their Elizabeth and James line and sold exclusively at Sephora stores starting in January.

“We always knew we wanted to have a fragrance for this brand, because it’s very lifestyle,” Ashley told Women’s Wear Daily. “We felt that between the brand Elizabeth and James and Sephora that we were really speaking together directly to our customer. We felt that was a really good place to start exploring the world of fragrance and beauty.”

The twins chose Nirvana because, as Ashley explained to WWD, “to us, this was really about a moment—and what’s that one word that’s going to define that one moment where you feel comfortable, sexy and at ease with yourself?”

Nirvana Black features notes of violet, sandalwood, and vanilla, while Nirvana White is a mesh of peony, muguet, and musk.

Elizabeth and James Nirvana eaux de parfum will be available in three sizes: 50 ml. for $ 75, 30 ml. for $ 55 and $ 22 for a rollerball applicator.

Meanwhile, Jay Z is also taking the fragrance industry by storm: The rap mogul will launch his first men’s eau de toilette, “Gold Jay Z” on Black Friday at major department stores across the U.S.

The men’s fragrance will be packaged in a gold-topped white bottle and coordinating box. The cap features engraved terms that inspired the cologne: “Power,” “Pride,” “Confidence,” “Strength,” “Success,” and “Courage.”
